Publication number: 20130000814Abstract: Doped adhesive tape is used during the manufacture of aircraft, including positioning marks, covering orifices from debris, allowing locations to be marked. Any doped adhesive tape inadvertently left in sub-assemblies during the manufacturing process can be detected using backscatter X-ray inspection technology. Detection is facilitated in one embodiment by making the tape thicker, to produce an increased mass density, and in another embodiment by adding a dopant comprising an element that is readily detected by the backscatter X-ray technology. The element can be iodine, and can be incorporated into the backing layer or the adhesive layer of the tape during manufacturing. The use of both thicker tape and a dopant can be used in combination to facilitate detection. If the doped adhesive tape is detected after components are assembled using a backscatter X-ray inspection device, then the doped adhesive tape is removed.Type: ApplicationFiled: July 1, 2011Publication date: January 3, 2013Inventors: Chin H.

Patent number: 8021518Abstract: The invention provides a method of increasing the absorbency of an absorbent article. The method includes introducing a super-absorbent polymer composition to a paper web in a papermaking process to increase the absorbent capacity of an absorbent article made in the process. The polymer composition includes a super-absorbent polymer and a cross-linking agent applied to the paper web. The paper web is then subjected to heat in a heated drum or a through-air drier to cure or cross-link the super-absorbent polymer.Type: GrantFiled: November 30, 2006Date of Patent: September 20, 2011Assignee: Nalco CompanyInventors: Gary S. Furman, Laurence S. Bonday, Shiby John

Patent number: 8007638Abstract: A method of manufacturing a cellulosic sheet having at least one of hydrophobic and oleophobic properties comprises the steps of depositing a stock of cellulosic fibers onto at least one forming fabric at an impingement zone and forming a web therefrom in a formation process; combining a water-based composition comprising an adhesion promoter, an organic nanoparticulate polymer and a fluorocarbon with the web at a preselected combination stage prior to a heating stage at which the web is subjected to a temperature exceeding 60° C.; and heat-curing the composition with the web during a drying process. A water-based composition for imparting at least one of hydrophobic and oleophobic properties to a cellulosic sheet during manufacture comprises an adhesion promoter, an organic nanoparticulate polymer and a fluorocarbon. A cellulosic sheet or layer thereof has at least one of hydrophobic and oleophobic properties. Improved resistance of cellulosic sheets to oil or water is obtained.Type: GrantFiled: July 4, 2006Date of Patent: August 30, 2011Assignee: AstenJohnson, Inc.Inventors: Samuel Baker, Jackson Graham, Dietmar Wirtz
